Please please help me out with this. I am trying to find a software/program that I could use the simulate the scattering effect of light when it strikes gas particles moving at supersonic speeds? Please help me as I have no idea what to use. I have googled several searches but I could find nothing. Please help. thanks a lot.

    $\begingroup$ I was trying to find similar software, physics.stackexchange.com/questions/5086/… But your requirements are even more difficult :-) So if you would find something amazing - let me know ;-) $\endgroup$ – BarsMonster Jun 18 '11 at 23:09

I would think you can decouple those two problems, since the respective timescales are very different - particles at supersonic speed are still as good as static for photons moving at lightspeed.

So I'd say find separate software for both - Fluent or OpenFoam for the CFD as per BarsMonster's linked question, and some raytracing package for the scattering simulation. I'm not knowledgeable in that regard, but Blender may be worth a shot.
